CreateCategory taking a ***LONG*** time - problem with EmitAdded?

[Warren Baird <photogeekmtl gmail com>]

Hi all,

I've been experimenting more with my tag import code, using the 
F_SPOT_QUERY branch and I've discovered that creating new categories can 
take a really long time.    I've seen it take several minutes to process 
the call to tag_store.CreateCategory() - and it looks like most of that 
time is spent in the call to EmitAdded (new_category) in the 
CreateCategory call.

I haven't had the time yet to look any deeper --- Are there known 
performance issues with EmitAdded?  I haven't tried this in cvs HEAD, 
but I didn't notice this when I was working with the 0.1.11 snapshot - 
is this specific to the F_SPOT_QUERY branch?

From the name, I assume EmitAdded is intended to notify other parts of 
f-spot that a new category was added...  is this necessary during the 
import phase?   Could we add an optional argument that turns this off?

Any other suggestions?   Even just importing a few hundred pics with a 
variety of tags can take a *LONG* time with this delay...

Thanks,

Warren
